| Light levels are the most important factor in flowering orchids.
Phals can flower in low light about 1500 foot candles
Most dendrobiums like more light in the 2500-4000 range.
Mobiles can take all day direct sun. The Hawaii growers give them full sun all day without any shade ever. This would be around 6-8000 foot candles.
laturia dendrobiums from New Guinae grow well in low light comparable to phals. Den spectabile would do well in your bathroom as well as any of the hybrids of spectabile, convolutum etc. These will not be easy to find and moderately expensive about double the price of common dens.
